To ,all whom it may concern:

Be it known that I, GRENVILLE M. WEEKS,

a citizen of the United States, residing at Newark, inthe county ofEssex and State of can cooler. A

The improvements consist in a less expen` sive and more convenientadjustment of a Ventilating tube, enough larger to enable itr yto beadapted to additional useful purposes. That which is new in connec ion4with the ventilatingtube specifically is t at the ventilationi-t,provides ispniore. perfect by reason of 'haviiigfwhat :is inot in ftheoriginal tulo'e,V

, mamely: openings into -it from vthe 'inside disk perforated like a -peo s airspacel r around the ltop part ,ofthe -neck of the milk can, .orsimilar fluid holding vessel, where the most Warmth and confined airis'-l and Where confined fiuids require venti-lation to guard againstgerm growthfostered by the stagnation resulting from confined airabove acertain temperature in'vessels holding milk or other drinkable fluids.

A second improvementis `provided by a which may be pivoted t fde over orhinged to shut down and cover'tlie exposed o en top of said tube, andthus guard against ust or dirt falling into it. Interference with properventilation is avoided by the cover acting as a perforated screenagainst dust and outside particles, or by a hasp like projection keepingthe disk around itsv circumference edge a fraction of -an inch' abovethe to edges of the tube'over which it projects, al owing a seam-likespacefor exit of animalheat-air to escape up and out of the can, whilethe to lis roofed in to keep dirt and dust from fal ing into the milkcan.

A third im rovement consists in the ventilating tube eing projectedawafrom full contact withthe ice chamber, t ough the center of whiehitpassedin the patent above named, by this latter arrangement now-offered,the tube is placed in the warmest part of the upper end of the milk-can,and made of a diameter sufficient to admit a milk inspeetors thermometerat the lace where the is warmest, and at suc location, if it registersas low a temperature as the State specification or Letters Patent.Application filed August 16, 1907.

law requires, the' rest is sure'to be as low, if

not lower. This tube device enables the legal milk inspector to test themilk without the exposure to dirt and dust the wind might blow into amilk can, if its cover had to be removed for the inspector to make hisex` ainination.

Afourth improvement, is an annular vreservoir, extending about thecircumference of the cover and resting on the shoulder lof the milk can;from the'bottom of this vannular' or ring-like reservoir the wateraccumulating from themelting ice may be withdrawn through a plug orscrew-cap o ening' in its bottom ring, and by lifting the li; thefilling of this annular reservoir with icemay he renewed without lifting.off the cover for the emptyingl of .water in renewiiigspace :for theice refilling.

A+- fifth im rarement fin @sensation with this tu-beds y;te ,of lnicksor slots lop.- `-positeleaehother-in theftop.edgeofthetube,

into which the adjustablecross handle of the c reaminixing rod may rest,and at the same time hold thedisk-dasher at the bottoni 'of the rod in afioating position instead of its 4restiri. i,'jo1i'the `bottom of themilk can'and forming a fixed milkl line or Aseam-for germ A .sixthimprovement in this refrigerating germegrowth-checking'milk can, is inhaving the bottomof the can stamped into a more concave form `withinthan is usual in the present can form, whose more acute angle seam atthe circumference bottom juncture with the can forms a nesting place forthe growth of germs more difficult to smoothly polish and cleanse thanmy devised obtuse angle at'this edge, which provides for a more perfectcleansing of cans from any possible eft over germs This inventionaffords further economy iiiasmuch as it saves the cost of manufacture ofice boxes heretofore in use and also the space taken up by said iceboxes. The trouble of cleaning an ice box is also avoided. Thisinvention is set forth in the following specication and claim andillustrated in the annexed drawing in which z- Figure 1 is a sectionalelevation of a can with cover embodying this invention. Fig. 2 is asection along a: :c Fig.` 1,.- Fig. Sis a section along 'y y Fig. 1.Fig. 4 shows a modication of the invention.

The letter indicates a receptacle or milk can and b is a` cover. Thiscover has a lid c hinged at d and with a fasteningor clasp e or as partof the cover.

A Ventilating tube h has openings rleading thereinto from the side andthis tube is connected or carried by a web c on the inner air chamber.As heat accumulates at the upper part of the can or receptacle it canrea ily escape through the tube. As such tube is at one side of oroutside the ice chamber g the l heat'passing through the tube doesnottend to melt the ice. rlhe two ice 'chambers with the tube could beformed of one piece of metal or material.. An auxiliary lidm givesaccess to the tube. This auxiliary lid can be opened Without opening themain lid. This auxiliary lid can hinge or swivel. perforated forventilation Fig. lhor by a boss or lug or bend of the auxiliary lid thelatter When closed can leave a lateral space for ventilation Fig. 4.

The tube h when uncovered can serve for the introduction of aninstrument for example a thermometer or any testing or in-v spectiondesired without opening the entire top of the can or receptacle. Or amixer or cream dasher can be inserted through the tube so that'if milkis drawn off ata stop cock a, the milk by aid of the mixer can firstbe'agitated to avoid quantities that have no l uniformity being drawnoff.

.4 avoid:

The top of tube h is notched or, shouldered so that the dasher or mixero can be left suspended in they can clear of the bottom to germsadhering to thecan or to the mixer.v

Itv can bel The cock or faucet plug uis screw threaded to be attached tothe tapped outlet p. This/ plug has a teat g which as it screws homeengages a depression in a rotary mutilated disk r which being turned tooverlap the fixed half disk s will open the outlet. unscrewing of thefaucet will reclose the rotary disk section to shut oil the outlet. Ascrew cap t can be applied when the faucet is taken off. c

rl'he melted ice can be drawn oil' fromA the cover by opening the plugor screw cap a.

Vhat I claim is 1. A can or receptacle having a shoulder, a cover havingan annular reservoir extending about the circumference of the cover andresting on the shoulder, and a lid for allowing access to the reservoirwithout displacing the cover.

2. A can or receptacle having a shoulder,

a cover having an annular reservoir extending about the circumference ofthe cover and yresting on the shoulder, and a lid for allowing access tothe reservoir without displacing the cover said reservoirhaving anoutlet means for the drippings or melted ice.

3. A device of the kind described provided with a cover having an icechamber and an inspection tube giving access for inspection and tes-ts,said tube having shoulder or rest portions for sustaining a testing orother instrument. f
